Why are yawns infectious?

Although there is no scientific consensus about why we did, theory shows that when people are tired, we are giving the best to deep breath, causing us t accumulation of carbon dioxide in the body

I Douglas Parham, scientist and associate professor at the Department of Communication and Disorders at Wichita State University, gulls could be special type of breathing We accumulate oxygen quickly, while being exposed to carbon dioxide, even more than deep breathing.

Too much carbon dioxide and other chemical changes, such as oxygen collapse or an increase in a compound called adenosine, could also act as "shout doors". These chemicals send a signal that causes seagulls. When weeping, we compress the facial muscles, bringing blood that has been enriched with oxygen to the brain.

Other theories claim that the purpose of yawning is cool the brain or stretch the internal organs like tissues and lungs, which helps the body to animate itself. "Although we are a fundamental part of our lives, there is information about crying out," he said. Thomas Scammell, a neurologist at Harvard Medical School studying sleep.

Our primitive reflex is among many animals originating from the brain. Because humans are similar to other mammals (and also birds and reptiles), it makes sense that most animals are blowing. In fact, birds, reptiles, mammals and some sharks can cry, and animals with larger brains tend to cry longer.

Dogs are actually infected by humans, not by other dogs, suggesting that they could only be something after we started growing them to be more friendly to people.

Why are they infectious?

Although yawns are still mysterious, the infection factor is not. According to a study conducted by the University of Maryland After seeing someone annoying, the likelihood of doing it increases six times.

For experts, it could be a phenomenon of the name social reflex, a behavior associated with neurons in the brain, where organisms mimic the actions of others. Other behaviors belong to this category, such as scratching, crossing the legs and laughing.

It is common for social animals, like humans, to copy each other to adapt to behaviors, especially when that behavior is something that might be useful to survive. That's why some research focuses on whether infectious gulls are associated with empathy or our ability to understand and share what other people feel.

"Empathy can be defined by the ability to understand, share and be affected by the states or other people's emotions. So, if you see someone making you make you shout in response, this action could be placed within an empathy category, "he explained. Andrew C. Gallup, assistant professor of psychology at SUNY Polytechnic Institute in Utica, New York. Some studies try to reveal whether people and animals with more empathy are more likely to have their birds. But Gallup, researching the practice for over 10 years, argues that more study is needed to be safe.

There may be a big (big breath and stretch in your sardrums, then breathing out big) serving. Cool the brain or other parts of your body. It could also have something to do with the regulate the amount of oxygen in blood. It could even be reflex that serves to keep the body's warning when one is tired or distracted.

"There are many other behaviors that are contagious, such as laughter and itching," he said. Gallup. "As yawning, these responses can be activated reliably by getting participants to watch videos of other people who perform them."
